Certificate Generator

Live for a Cause — TikTok fundraiser certificates. Layered HTML5 Canvas renderer, data-driven, exportable at print quality (2480×3508, A4 @ 300 DPI).

Participant Full name TikTok handle Role Avatar image (upload — best for export) or Avatar URL

If no image is provided, an elegant placeholder silhouette is drawn automatically. Remote URLs need CORS support to export correctly — uploading a file always works.

Event Event title Dates Beneficiary Certificate ID (manual)

Backend (optional) Issue & save via backend

When on, each certificate gets a real, unique, database-backed ID from your deployed Worker, and the rendered PNG is uploaded so the QR code actually verifies. When off, the Certificate ID field above is used as-is and nothing is saved anywhere — handy for design/offline preview.

API base URL Issuer API key

Sent only as a request header to the URL above — never stored or written anywhere by this page.
